Specification of Letters Patent.

Patented Oct. 13, 1908.

Application filed August 19, 1907., Serial No. 389,145.

To all whom it may concern:

Pittsburg,in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Car-Stakes, of which the'following is a-specification.

My invention relates to improvements in car-stakes, and more particularly to a new and im roved metallic telescopic car-stake designe to extend above the floor and sides of a car and to secure the lading on all kinds of open freight-cars. 4

To this end the present invention consists in a new and improved telescopic car-stake, in the novel features of construction, and in the combination of-parts all as fully hereinafter described and-claimed. I

In the accompanying drawings which illustrate an application of my invention, Figure 1 is a central vertical sectional view of a carstake embodying my invention showing the stake extended; Fig. 2 a similar view sh0wing thestake closed; Figs. 3, 4, and 5 elevational views of telescopic members; Figs. 6, 7, and 8 detail lan views; Fig. 9 an enlarged detail sectiona view; Fig. 10 a cross section taken on line 10-10of Fig. 9; Fig. 11 an elevational view particularly showing the manner of attaching the stake to a side of a car; Fig. 12 a detail view of upper end of the outer telescopic-member; Fig. same; and Fig. filler-blocks employed in securing the stake to the sides of a car. I 1

Referring to the drawings, 1 designates the floor of a car, and 2 a side.

My car-stake as illustrated and as preferred comprises three telescopic tubular members 3, 4 and 5, each provided at its lower end with an annular flanged or enlarged portion 6. Members 3 and 4 fit into the outer or pocket-member 5 and are adapted to be moved therein to open and close the stake. The upper ends of each of the members 5 and 4 are contracted or swaged and are also formed with a bulge as indicated by the numerals 5 and 4 In addition thereto, the respective members 5 and 4 are cutaway as s own at 7 and 8 respectively to form a led e or seat for the respective projections 9 and 10 formed on the members 4 and 3. As shown by Fig. 1 when the stake is in an extended position and the members 4 and 3 turned to the proper position for locking them in the extended position, the projection 9 of member 4 rests upon the ledge of Zby' its own weight gagement with the flanged a ber 5, and the flanged portion of member 3 i V member 5 and the projection 10 of member 3 Be it known that I, JAY F. TOWNS ND, of upon the ledge of member 4.

To limit the upward movement of the member 4, I indent the member 5 as shown at 1 1 and to limit the upward travel of the member 3 a similar inidentation 12 is formed on the member 4.

These respective indentations. 11 and 12 engage the annular flanges 6 of the res ective imembers 4 and 3 should said mem ers be {)aised or extended too far within the mem- 2 er 5.

j Another important function of the annular flanges or enlarged portions 6 of members 4 l and 3 is that, when a-car is dumped or turned 1 upside down the flange of member 4 is thrown automatically into en portion of mem is locked automatically as above described lwith that of member 4, thereby preventing saidmembers 4 and'3' from being projected from the member 5.

The stake as illustrated is secured to the I sidefiof the carby means of'a lower metallic strap 13 and an upper strap 14 which straps are in turn attached to'the side by means of rivets 15.

Interposed between said side 2 L and the stake and supported by the straps,

I employ saddles or ii er-blocks 16, the form I: of these saddles is particularly shown by Fig.

13 a lan of :14 14 detail views of sa dles or 3 The contracted or swaged portion of the lower and intermediate-members 5 and 4 to gether with the metallic plug fitted into the upper end of the top-member 3, provide a construction that will exclude dirt and other foreign substances from the stake.

What I claim is:

' 1. A car-stake having a plurality of telescopic-members comprising a bottom-member having a contracted upper end-portion, and an intermediate-member having a projection adapted to engage the contracted portion of the bottom-member.

2. A car-stake having a plurality of tubular telescopic-members comprising a lowermember formed with a contracted upper end and a seat formed on said contracted portion, and an intermediate-member having a projection adapted to engagethe seat.

3. A car-stake comprlsmg a tubular mem-- 5. A carstake comprising a plurality of tubular telescopic members each formed with an annular flange at its lower end.

6. A car-stake having a plurality of tubular telescopic-members comprising a lowermember formed with a contracted upper end, an intermediate-member having a projection, said contracted upper end formed with a bulge and a seat for the projection of the intermediate-member.

7. A car-stake having a plurality of tubular telescopic-members comprising a bottom member having a contracted upper end-portion, an intermediate-member having a con tracted upper end-portion and a projection adapted to engage the contracted portion of the bottom-member, and an upper-member having a projection adapted to engage the contracted portion of the intermediatemember.

8. A car-stake having a plurality of telescopic-members comprising a bottom-member formed with a lower annular flange and with a contracted upper end-portion, and an intermediate-member having a lower annular flange and a projection adapted to engage the contracted portion of the bottom-member.

9. A ear-stake having a plurality of telescopic-members comprising a bottom-member having a contracted upper end-portion and a lower annular flange, an intermediatehaving a contracted upper end-port1on a lower annular flange and a projection adaptedto engage the contracted portion of the lower-member, and an upper-member aving an annular flange and a projection adapted to engage the contracted portion of the intermediate-member.

10. A car-stake having a plurality of tubular telescopic-members comprising a lower- I member having a contracted upper end-port1on formed with a bulge and a seat, an intermediate-member having a contracted upper and with a projection adapted to engage the seat of the bottom-member, and a top-member formed with a projection adapted to engage the seat of the intermediate-member.

car-stake comprising a tubular member formed with a contracted upper end and an annular flange at its lower end.

12. A car-stake comprising a member having a contracted upper end-portion, and a second member having a projection adapted to engage the contracted portion of the first member.

13. A car-stake having two telescopicmembers, one member having a contracted upper end-portion and a lower ann nlar flange, and the second member having a projectiml adapted to engage the contracted portion of the first member.

14. A car-stake having two telescopicmembers each formed with an annular flange at its lower end, one member being formed with a contracted portion, and the other member with a projection adapted to engage the contracted portion of the first member.

15. A car-stake having two telescopicmembers each formed with a contracted upper end-portion and a lower annular flange, one member having a projection adapted to engage the contracted portion of the other member.

In testimony whereof I alfiX my signature in presence of two witnesses.
